  By the way, the above prior art does not search for and guide a multimodal route in consideration of a travelable distance depending on the remaining amount of fuel at the departure point of the internal combustion engine vehicle. Therefore, if the above conventional technique is simply applied to an electric vehicle having an electric motor as a travel power source, the following situation may occur.

  That is, when the above-described conventional technology is simply applied to an electric vehicle, a multimodal route is searched and guided without considering the cruising distance depending on the state of charge at the departure point of the electric vehicle. Then, even if the charge amount of the electric vehicle at the departure place is low and the cruising distance is short, the electric vehicle parking lot provided near the boarding place of public transportation that is more than the cruising distance from the departure place It is also possible to search and guide a multimodal route including the route. In this case, the electric vehicle cannot reach the electric vehicle parking lot on the multimodal route due to insufficient charge amount.

  The present invention has been made in view of the above circumstances, and its purpose is to provide a route guidance system capable of searching and guiding a multimodal route taking into account the cruising range depending on the state of charge of the electric vehicle at the departure point, An object of the present invention is to provide a vehicle management center that constitutes this route guidance system, and an in-vehicle device constituting this route guidance system.

In order to achieve such an object, according to the first aspect of the present invention, departure point information acquisition means for acquiring departure point information, which is information indicating a departure point of a user of an electric vehicle having an electric motor as a driving power source, and the electric vehicle Stop location information acquisition means for acquiring stop location information that is information indicating the stop location of the user, destination information acquisition means for acquiring destination information that is information indicating the destination of the user of the electric vehicle, and the electric vehicle Cruising distance calculation means for calculating the cruising distance of the electric vehicle based on the charging state information which is information indicating the charging state of the vehicle, information indicating the departure point information, stopover information, destination information, and cruising distance On the basis of the cruising range information, the electric vehicle and a public transportation system where a parking lot for an electric vehicle, which is a parking lot with a charging facility for charging the electric vehicle, is provided near the landing area. Was, a route to the destination that has passed through the area stop-off from the starting point, use the electric vehicle for from the starting point to the parking lot for an electric vehicle, the back and forth between the parking lot and stop-off place for an electric vehicle Is a route using electric transport from the parking lot for electric vehicles to the destination using electric transportation, and the amount of charge necessary to reach the destination can be charged by the scheduled time Multimodal route search means for searching for a multimodal route including a route in which a parking lot for an electric vehicle is within a cruising distance at the departure location from the departure location, and current location information which is information indicating the current location of the electric vehicle and a current position information acquiring means for acquiring, based on the multimodal route information is information indicating the current position information and the multimodal route, guides the multimodal route path The multimodal route search means includes a scheduled time information acquisition unit that acquires scheduled time information that is information indicating a scheduled time for the user of the electric vehicle to return from the stop to the electric vehicle parking lot. Based on the scheduled time information in addition to the location information, stopover information, destination information, and cruising range information, the amount of charge required to reach the destination is charged by the scheduled time as a multimodal route. A multimodal route including a route to an electric vehicle parking lot that can be searched .

In the above configuration as the route guidance system, the multimodal route searching means is based on the cruising range information and the scheduled time information in addition to the departure point information , the stopover information, and the destination information. Is searched for a multimodal route including a route located within a cruising distance at the departure point from the departure point. Therefore, unlike the above-described prior art in which the multimodal route is not searched and guided in consideration of the travelable distance according to the fuel state of the internal combustion engine vehicle at the departure point, the cruising distance due to the charged state of the electric vehicle at the departure point is considered. It becomes possible to search and guide the multimodal route. As a result, it is possible to reduce the occurrence of a situation in which the electric vehicle cannot reach the electric vehicle parking lot on the multimodal route due to insufficient charge amount.

  By the way, the vicinity of the boarding area is separated from the boarding area by a distance that can reach the boarding area of public transportation on foot (for example, a distance of about “several minutes” to “10 minutes” on foot). Means range. In addition, in the parking lot for electric vehicles provided near the boarding area, facilities attached to public transport (for example, stations attached to trains, bus stops attached to buses, airports attached to airplanes, etc.) Includes a parking lot for electric vehicles.

In addition, the multimodal route searching means searches for a multimodal route including a route to a parking lot for an electric vehicle that can charge the amount of charge necessary to reach the destination by the scheduled time. When the vehicle user leaves the parking lot for the electric vehicle toward the destination, the user does not have to worry about a short cruising distance due to a lack of charge. Thereby, it becomes possible to eliminate the psychological anxiety of the user of the electric vehicle.

In order to achieve the above object, in the invention described in claim 2 , departure point information acquisition means for acquiring departure point information which is information indicating a departure point of a user of an electric vehicle having an electric motor as a driving power source ; a destination information acquiring section for acquiring destination information indicating a destination of the user of the electric dynamic vehicle, based on the charging state information indicating the state of charge of the electric vehicle, the cruising distance of the electric vehicle a traveling enable distance calculation means for calculating, based on the cruising distance information indicating departure information, their destinations information, and the cruising distance, an electric vehicle, the charging facility for charging the electric vehicle installation This is a route from the departure point to the destination via the stop, where the electric vehicle parking lot, which is a designated parking lot, is used in combination with public transportation provided near the boarding area. By the parking lot Have to use the electric vehicle is, is a path to use the public transport for the parking lot for the power dynamic vehicle to the destination, and, in the parking lot for an electric vehicle is in the cruising distance in the place of departure from the starting point A multi-modal route search means for searching for a multi-modal route including a route that is located, and a current location information acquisition means for acquiring current location information that is information indicating the current location of the electric vehicle, and present location information and information indicating the multi-modal route. It is characterized in that a multimodal route is guided based on certain multimodal route information.

In the above configuration as a route guidance system, a multimodal route search means, in addition to the starting Chijo Ho及 beauty destination information, cruising distance also on the basis of the information, parking electric vehicle this departure from the departure point A multimodal route including a route located within the cruising range is searched. Therefore, unlike the above-described prior art in which the multimodal route is not searched and guided in consideration of the travelable distance according to the fuel state of the internal combustion engine vehicle at the departure point, the cruising distance due to the charged state of the electric vehicle at the departure point is considered. It becomes possible to search and guide the multimodal route. As a result, it is possible to reduce the occurrence of a situation in which the electric vehicle cannot reach the electric vehicle parking lot on the multimodal route due to insufficient charge amount.

By the way, the vicinity of the boarding area is separated from the boarding area by a distance that can reach the boarding area of public transportation on foot (for example, a distance of about “several minutes” to “10 minutes” on foot). Means range. In addition, in the parking lot for electric vehicles provided near the boarding area, facilities attached to public transport (for example, stations attached to trains, bus stops attached to buses, airports attached to airplanes, etc.) Includes a parking lot for electric vehicles.
By the way, the electric vehicle has the following characteristics as compared with the internal combustion engine vehicle. That is, in the internal combustion engine vehicle, the degree of decrease in the remaining amount of fuel may be lowered depending on the traveling state and the traveling route, and the travelable distance may be increased. Similarly, even in an electric vehicle, the degree of decrease in the amount of charge is reduced depending on the driving situation and the driving route, and the cruising range may be increased. However, in an internal combustion engine vehicle, the remaining amount of fuel always decreases as the vehicle travels. Therefore, the travelable distance does not increase significantly. On the other hand, in an electric vehicle, for example, when traveling on a road with a downward slope, the amount of charge may increase rather than decrease. As a result, the cruising range may be significantly increased.
Therefore, in the invention described in claim 2, the multimodal route searching means can travel from the current location to the current location as a multimodal route based on the fact that a predetermined re-search condition is established. The multimodal route including the route located within the distance was re-searched.
In the above configuration as the route guidance system, the multimodal route search means, based on the fact that the predetermined re-search condition is established, the electric vehicle parking lot is within the cruising distance at the current location from the current location as the multimodal route. Re-search the multimodal route including the route that is located. Therefore, even when the cruising range changes because the traveling environment of the electric vehicle is not as planned, the electric vehicle can reach the electric vehicle parking lot, so that the user can reach the destination. Become. In particular, when the cruising distance of an electric vehicle has increased significantly, the public transportation system is not used based on the initially searched multimodal route, but it is public at the boarding / exiting point closer to the destination. It becomes possible to use transportation facilities, and as a result, the usage fee for public transportation facilities can be reduced. In this way, when the cruising distance increases, the extended cruising distance can be effectively utilized.
Incidentally, the prior art for re-searching the route to the destination based on the fact that the route has been deviated during the route guidance to the destination is well known. In such a known prior art, re-search is performed with priority given to returning to the route that was being guided, whereas in the above configuration, priority is given to getting closer to the getting-on / off place nearest to the destination. A re-search will be performed.
In addition, the number of re-search points acquired by user operation is usually smaller than the number of branch points. Therefore, the frequency with which the multimodal route is re-searched is reduced. In addition, since the re-search area including the branch point may include a plurality of branch points, the calculation load related to the route guidance system can be further reduced.

In the configuration described in claim 2, as in the invention described in claim 3, fare information acquisition means for acquiring fare information that is information indicating the fare of public transportation is provided, and the multimodal route search means includes In addition to departure point information, destination information, and cruising distance information, as a multimodal route, the fare to the nearest boarding point for the electric vehicle parking lot is the cheapest as a multimodal route We decided to search for a multimodal route including the route. This ensures the lowest cost of using public transportation.

  By the way, the electric vehicle has the following characteristics as compared with the internal combustion engine vehicle. That is, in the internal combustion engine vehicle, the degree of decrease in the remaining amount of fuel may be lowered depending on the traveling state and the traveling route, and the travelable distance may be increased. Similarly, even in an electric vehicle, the degree of decrease in the amount of charge is reduced depending on the driving situation and the driving route, and the cruising range may be increased. However, in an internal combustion engine vehicle, the remaining amount of fuel always decreases as the vehicle travels. Therefore, the travelable distance does not increase significantly. On the other hand, in an electric vehicle, for example, when traveling on a road with a downward slope, the amount of charge may increase rather than decrease. As a result, the cruising range may be significantly increased.

Therefore, in the configuration described in claim 1, in the invention according to claim 4, multimodal route search section, based on the predetermined re-search condition is satisfied, the multi-modal path, electrostatic the dynamic vehicle The multi-modal route including the route where the parking lot is located within the cruising distance in the current location from the current location is re-searched.

  Even in the above-described configuration as the route guidance system, the multimodal route search means, based on the fact that the predetermined re-search condition is established, the electric vehicle parking lot is within the cruising distance from the current location as the multimodal route. Re-search the multimodal route including the route that is located. Therefore, even when the cruising range changes because the traveling environment of the electric vehicle is not as planned, the electric vehicle can reach the electric vehicle parking lot, so that the user can reach the destination. Become. In particular, when the cruising range of electric vehicles has increased significantly, the public transportation is not used on the basis of the multimodal route that was originally searched for. It becomes possible to use transportation facilities, and as a result, the usage fee for public transportation facilities can be reduced. In this way, when the cruising distance increases, the extended cruising distance can be effectively utilized.

  Incidentally, the prior art for re-searching the route to the destination based on the fact that the route has been deviated during the route guidance to the destination is well known. In such a known prior art, a re-search is performed with priority given to returning to the route that has been guided, whereas with the above configuration, a re-search is performed with priority given to closer to the nearest facility side of the stop. Will be.

In the configuration described in claim 4 , as in the invention described in claim 5 , fare information acquisition means for acquiring fare information that is information indicating the fare of public transportation is provided, and the multimodal route search means includes In addition to departure point information, stopover information, destination information, and cruising range information, based on fare information, as a multi-modal route, the fare to the nearest stop for the stopover is as follows. We decided to search for multimodal routes including the cheapest route. This ensures the lowest cost of using public transportation.

As in the configuration according to claim 8 , the multimodal route search means sets the multimodal route as a re-search condition every time a certain time (for example, “10 minutes”) elapses after searching the multimodal route. It is good also as re-searching. However, when such a configuration is adopted, a multimodal route is frequently re-searched, so that a calculation load related to the route guidance system becomes large.

Therefore, in the configuration described in claim 2 or 3 , as in the invention described in claim 6 , the multimodal route search means uses the electric vehicle at a branch point on the multimodal route being guided as a re-search condition. The multimodal route may be re-searched based on the fact that has arrived. Thereby, since the frequency with which a multimodal route is re-searched is reduced, the calculation load concerning the route guidance system is reduced. Incidentally, a branch point on a multimodal route means an intersection.

Further, in the configuration according to any one of claims 2 , 3 , and 6 , as in the invention according to claim 7 , the multimodal route search means has a re-search condition on the multimodal route being guided. The multimodal route may be re-searched based on the fact that the electric vehicle has arrived around the electric vehicle parking lot. Here, the fact that the electric vehicle has reached the vicinity of the electric vehicle parking lot on the multimodal route being guided is a fixed distance (for example, centered on the electric vehicle parking lot on the multimodal route that has already started guidance) It means that the electric vehicle has reached a circle having a radius of “5 [km]”).

Moreover, in the structure in any one of the said Claims 1-8 , in the structure of Claim 9 , the charge electric energy prediction means which estimates the charge electric energy in the grid in which the parking lot for electric vehicles is included, and multi Based on the modal path information, a grid prediction unit that predicts a grid that charges the charging power amount, charging power amount prediction information that is information indicating the charging power amount in the grid predicted by the charging power amount prediction unit, and grid prediction It is provided with the prediction information provision means which provides the grid information which is the information which shows the grid estimated by the means to the grid electric power feeding management center which manages the electric power feeding to each grid. Thereby, it becomes possible to provide the charging power amount prediction information and the grid information to the grid power supply management center, that is, the power company, and the power company can add the charging power amount prediction information and the grid information provided from the route guidance system. Based on this, it is possible to make a power supply plan in units of grids, and to supply power to each grid according to the power supply plan that has been established, and in turn, it is possible to supply power to each grid to suit the power needs. It becomes like this.

The invention described in claims 10 and 11 is a vehicle management center constituting the route guidance system described in claims 1 and 2 , and the invention described in claims 12 and 13 is described in the claims 1 and 2. 2 is an in-vehicle device constituting the route guidance system according to 2 ;

The center-side storage unit 21 stores location information on the station, location information on the EV parking lot, map information including road information, and fare information that is information indicating the fare of public transportation. In the present embodiment, a train is adopted as a public transportation used in combination with the EV vehicle C, but the present invention is not limited to this. In addition, for example, a bus may be adopted as a public transportation used in combination with the EV vehicle C. When the bus is adopted, the center-side storage unit 21 stores the location information of the bus stop, the map information including the location information of the EV parking lot that the bus stop has, and the bus fare information. In addition, for example, an airplane may be adopted as a public transportation used in combination with the EV vehicle C. When an airplane is adopted, the center-side storage unit 21 stores airport position information, map information including position information of an EV parking lot that the airport has, and airplane fare information.

  The center-side control unit 23 is connected to a center-side communication unit 22 configured with an appropriate antenna, and performs wireless communication with the in-vehicle device 10 using the center-side communication unit 22. The center-side control unit 23 corresponds to the multimodal route search means described in the claims.

  Further, when the center side control unit 23 receives the current location information, destination information, or SOC information by the center side communication unit 22, the received information is stored in the center side storage unit 21 according to the vehicle ID of the EV vehicle C. Remember. In this way, the vehicle management center 20 manages the plurality of EV vehicles C on which the in-vehicle device 10 is mounted.

  When the center side communication unit 22 receives the route search execution instruction, the center side control unit 23 stores the current location information, destination information, cruising distance information, and fare information, and the center side storage unit 21. A route from the current location to the destination using both the EV vehicle C and the train based on the map information that is used, and from the current location to the EV parking lot, the EV vehicle C is used and the station having the EV parking lot From the station to the nearest station of the destination, a train is used, and from the nearest station of the destination to the destination, a multimodal route, which is a route moving on foot, is searched.

  Specifically, the center side control unit 23 reads the fare information from the center side storage unit 21 based on the read fare information in addition to the current location information, the destination information, and the cruising range information. Among the EV parking lots that the station attached to the train has, it is an EV parking lot that is located within the cruising distance from the current location, and the EV parking lot that has the lowest train fare (fare) to the destination Search for a multimodal route including the route. When searching for a multimodal route, the center side control unit 23 transmits multimodal route information, which is information of the searched multimodal route, to the EV vehicle C by the center side communication unit 22. The center-side control unit 23 corresponds to the fare information acquisition unit described in the claims.

  Further, the center side control unit 23 has appropriate time measuring means (not shown) such as an internal timer, for example, and a fixed time (for example, “10 [minutes]”) has elapsed with reference to the time when the search for the multimodal route is completed. Then, the multimodal route is searched again. In this embodiment, the fact that a re-search condition that is a condition for re-searching for a multimodal route is established, that `` a certain period of time has elapsed with reference to the time when the search for the multimodal route is completed '' is adopted. Not limited to this. Other re-search conditions will be described in an embodiment described later.

  In the present embodiment, the center-side control unit 23 searches for a multimodal route starting from the current location of the EV vehicle C when the route search execution instruction is received, but is not limited thereto. It is also possible to set a point different from the current location as the starting point by 13 and search for a multimodal route that is a route from the set starting point to the destination. In other words, the departure point information may be different from the current location information.

  Moreover, the center side control part 23 estimates the charge amount in each EV parking lot based on the multimodal route information and SOC information of each EV vehicle C. Specifically, the center-side control unit 23 sets the “grid including the EV parking lot where each EV vehicle C is charged (grid information)” and “the time when each EV vehicle C arrives at the EV parking lot” as multimodal route information. From “SOC information”, the “charge amount necessary to charge each EV vehicle C to a predetermined target charging state (for example,“ 100% charging rate (ie, full charge) ”) is predicted. . The center side control part 23 estimates the charge amount in each EV parking lot based on the prediction result of the charge amount of each EV vehicle C, and charges in each grid based on the prediction result of the charge amount in each EV parking lot. Predict the amount of electricity. Then, the center-side control unit 23 transmits (provides) charge power amount prediction information, which is information on a prediction result of the charge power amount in each grid, to the grid power supply management center 30. The center-side control unit 23 corresponds to a charging power amount prediction unit, a grid prediction unit, and a prediction information providing unit described in the claims.

  Moreover, the center side control part 23 is connected to EV parking lots Pb and Pc, and sequentially acquires the full availability information that is information related to the full availability of the EV parking lots Pb and Pc.

  In this embodiment, “full charge state” is adopted as a predetermined target charge state determined in advance, but in addition to this, “state of a predetermined ratio of full charge (for example,“ 80% ”, etc.)” , Or “not charged” or the like may be adopted as the target charged state. Moreover, it is good also as inputting into the operation part 13 by user operation instead of determining beforehand. Further, the vehicle management center 20 may inquire the in-vehicle device 10 about the target charging state and prompt the input. The center-side control unit 23 corresponds to a charging power amount predicting unit described in the claims.

  Operations of the route guidance system 1 and the grid power supply management center 30 configured as described above will be described with reference to FIGS. 4 to 6 and FIG.

  FIG. 4 shows a processing procedure for the multimodal route guidance processing S100 executed by the in-vehicle device 10.

  When the execution of the multimodal route guidance process S100 is started, the in-vehicle device 10 first determines whether destination information and a route search execution instruction are input from the operation unit 13 as a determination process in step S101. Here, when the destination information and the route search execution instruction are not input (“No” in the determination process of step S101), the in-vehicle device 10 executes the determination process of step S101 again, while the destination information and When a route search execution instruction is input (“Yes” in the determination process of step S101), the in-vehicle device 10 proceeds to the subsequent process of step S103. When the process proceeds to step S103, the in-vehicle device 10 transmits a signal indicating destination information and a route search execution instruction to the vehicle management center 20, and the process proceeds to the subsequent step S105.

  When the process proceeds to step S105, the in-vehicle device 10 starts to sequentially transmit the current location information, the SOC information, and the cruising distance information to the vehicle management center 20, and then proceeds to the determination process in step S107. The in-vehicle device 10 continues to sequentially transmit the current location information, the SOC information, and the cruising distance information to the vehicle management center 20 until the execution of the multimodal route guidance process S100 is completed. At this time, the in-vehicle device 10 is repeatedly executed for a certain time (for example, “every five minutes”) that is sufficiently shorter than a certain time described later (see the determination process in step S215).

  In step S107, the in-vehicle device 10 determines whether the multimodal route information is received from the vehicle management center 20. Here, when the multimodal route information is not received (“No” in the determination process in step S107), the vehicle-mounted device 10 executes the determination process in step S107 again, while receiving the multimodal route information. ("Yes" in the determination process in step S107), the in-vehicle device 10 proceeds to the subsequent determination process in step 109.

  In step S109, the in-vehicle device 10 determines whether a route guidance start instruction is input from the operation unit 13. Here, when the route guidance start instruction is not input (“No” in the determination process of step S109), the in-vehicle device 10 executes the determination process of step S109 again, while the route guidance start instruction is input. If this is the case (“Yes” in the determination process of step S109), the in-vehicle device 10 proceeds to the subsequent process of step 111. If transfering to the process of step S111, the vehicle equipment 10 will perform route guidance of a multimodal route, and will transfer to the determination process of subsequent step S113.

  In step S113, the in-vehicle device 10 determines whether or not the multimodal route information re-searched from the vehicle management center 20 is received. Here, when the re-searched multimodal route information has not been received (“No” in the determination process in step S113), the vehicle-mounted device 10 continues the guidance of the multimodal route that has already started guidance, On the other hand, if the re-searched multimodal route information is received ("Yes" in the determination process in step S113), the in-vehicle device 10 proceeds to the subsequent determination process in step 115 and already starts guidance. The route guidance of the received multimodal route is executed in place of the multimodal route that has been performed, and the process proceeds to the determination process in the subsequent step S117.

  If transfering to the determination process of step S117, the vehicle-mounted device 10 determines whether or not the EV parking lot on the multimodal route has been reached. Here, when it is not determined that the vehicle has arrived (“No” in the determination process of step S117), the in-vehicle device 10 executes the determination process of step S113 again, while when it is determined that the vehicle has arrived (determination of step S117). In the process, “Yes”), the in-vehicle device 10 ends the route guidance of the multimodal route as the process of the subsequent step S119.

  When the multimodal route guidance is completed, the in-vehicle device 10 outputs a route guidance end notification indicating that the multimodal route guidance has been completed to the vehicle management center 20 as processing of the subsequent step S121, and this step S100. The process is terminated as it is.

  FIG. 5 shows a processing procedure for the multimodal route search process S200 executed by the vehicle management center 20.

  When the execution of the multimodal route search process S200 is started, the vehicle management center 20 first determines whether or not the center side communication unit 22 has received a signal indicating destination information and a route search execution instruction as the determination process of step S201. Judging. Here, when these signals indicating the destination information and the route guidance start instruction have not been received (“No” in the determination process of step S201), the vehicle management center 20 executes the determination process of step S201 again. On the other hand, when the destination information and a signal indicating a route search execution instruction are received (“Yes” in the determination process in step S201), the vehicle management center 20 proceeds to the subsequent process in step S203.

  If transfering to the process of step S203, the vehicle management center 20 will start reception of the present location information and cruising range information which are sequentially transmitted from the vehicle equipment 10, and will transfer to the process of subsequent step S205. The vehicle management center 20 continues to receive the current location information and the cruising range information sequentially until the multimodal route search process S200 is completed.

  The vehicle management center 20 reads the fare information from the center-side storage unit 21 as the processing of the subsequent step S205, and in addition to the destination information, the current location information, and the cruising distance information as the processing of the subsequent step S207, The route to the EV parking lot that is located within the cruising distance from the current location and has the lowest fare to the destination among the plurality of EV parking lots that the train has based on the information Search for a multimodal route containing.

  When the multimodal route is searched in this way, the vehicle management center 20 determines whether there is a vacancy in the EV parking lot included in the multimodal route searched in the previous step S207 as the determination processing in the subsequent step S209. Judge whether or not. Here, when it is determined that there is no vacancy in the EV parking lot (“No” in the determination processing in step S209), the vehicle management center 20 proceeds to the processing in the previous step S207, and a plurality of EV parking lots that the train has. Multi-modal including the route to the EV parking lot that is located within the cruising distance from the current location and the fare to the destination is the cheapest except for the EV parking lot where there was no vacancy Search the route again. On the other hand, when it is determined that there is a vacancy in the EV parking lot, the vehicle management center 20 determines the multimodal route searched in the process of the previous step S207 as the process of the subsequent step S211 and the process of the subsequent step S213 Then, the determined multimodal route information is transmitted to the in-vehicle device 10. Note that the processing in step S213 corresponds to the transmission means described in the claims.

  When the multimodal route information is transmitted, the vehicle management center 20 determines whether or not a predetermined time has elapsed since the determination of the multimodal route as the determination process in the subsequent step S215. Here, when a predetermined time has elapsed since the multimodal route was determined (“Yes” in the determination process of step S215), the vehicle management center 20 proceeds to the process of the previous step S207, and again the multimodal route. Explore. On the other hand, when a predetermined time has not elapsed since the multimodal route was determined (“No” in the determination process in step S215), the vehicle management center 20 proceeds to the subsequent determination process in step S217.

  In step S217, the vehicle management center 20 determines whether or not the route guidance has ended, that is, whether or not the route guidance end notification has been received. If the route guidance end notification has not been received (“No” in the determination process of step S217), the center control unit 23 executes the determination process of the previous step S215 again, while the route guidance end is completed. When the notification is received (“Yes” in the determination process in step S217), the center-side control unit 23 ends the process of the multimodal route search process S200 as it is.

  FIG. 6 shows a processing procedure for the charge amount prediction process S220 executed by the vehicle management center 20. It is assumed that the vehicle management center 20 has already executed the multimodal route search process S200 and has already acquired multimodal route information for each EV vehicle C managed by the vehicle management center 20.

  When the execution of the charge amount prediction process S220 is started, the vehicle management center 20 first starts the sequential reception of the SOC information sequentially transmitted from the in-vehicle device 10 as the process of step S221, and the multimodal as the process of the subsequent step S223. Based on the route information and the SOC information, the amount of charge necessary for each EV vehicle C to be fully charged is predicted. Each EV vehicle C includes an EV vehicle C parked in the EV parking lot and an EV vehicle C scheduled to arrive at the EV parking lot. When the charge amount of each EV vehicle C is predicted, the vehicle management center 20 predicts the charge amount in each EV parking lot based on the prediction result of the charge amount of each EV vehicle C as the process of subsequent step S225. When the charge amount in each EV parking lot is predicted, the vehicle management center 20 predicts the charging power in each grid based on the prediction result of the charge amount in each EV parking lot as the subsequent process of step S227. When the charging power in each grid is predicted, the vehicle management center 20 transmits charging power amount prediction information, which is information on the prediction result of the charging power amount in each grid, to the grid power supply management center 30 as processing of the subsequent step S229 ( provide. When the charge power amount prediction information is transmitted (provided) to the grid power supply management center 30, the vehicle management center 20 ends the charge amount prediction processing S220 as it is.

  FIG. 7 shows a processing procedure for power supply processing S320 executed by the grid power supply management center 30.

  When the power supply process is started, the grid power supply management center 30 determines whether or not the charging power prediction information is received from the vehicle management center 20 (that is, whether or not it is provided) as the determination process in step S321. . Here, when the charging power prediction information has not been received (“No” in the determination process of step S321), the grid power supply management center 30 executes the determination process of the previous step S321 again, while the charging power prediction information is not. If provided (“Yes” in the determination process of step S321), the grid power supply management center 30 proceeds to the subsequent process of step S323. When the process proceeds to step S323, the grid power supply management center 30 makes a power supply plan for each grid based on the charging power prediction information provided from the vehicle management center 20, and proceeds to the subsequent step S325. When the process proceeds to step S325, the grid power supply management center 30 supplies power to each grid in accordance with the power supply plan in units of grids established in the previous step S323. When power is supplied to each grid, the grid power supply management center 30 ends this power supply processing S320 as it is.

  An example of the operation of the route guidance system 1 configured as described above will be described with reference to FIG. As shown in FIG. 1 or as described above, the charging facility for charging the EV vehicle C is not installed in the parking lot Pa of the station Sa located in the grid G1, and the grid G2 Charging facilities for charging the EV vehicle C are respectively installed in the EV parking lot Pb of the station Sb located inside and the EV parking lot Pc of the station Sc located in the grid G3. The station Sd is the nearest station of the user of the EV vehicle C, the train fee between the station Sa and the station Sd is “500 yen”, the train fee between the station Sb and the station Sd is “400 yen”, The train fare between the station Sc and the station Sd is “250 yen”. Further, the branch points P11 to P16, the point P17, the parking lot Pa, and the EV parking lots Pb and Pc are separated by a distance a to a distance i and a distance c1 as shown in FIG. h + distance i)> (distance e + distance j). A branch point means an intersection.

  Here, the cruising distance La of the EV vehicle C at the branch point P11 is “(distance a + distance f) <(distance a + distance b + distance c + distance g) <distance cruising distance La <(distance a + distance b + distance c + distance d + distance”. It is assumed that it is calculated so as to satisfy the relationship of “e + distance j)”. In other words, although the parking lot Pa and the EV parking lot Pb are located within the cruising distance of the EV vehicle C at the branch point P11, the EV parking lot Pc is within the cruising distance of the EV vehicle C at the branch point P11. Assume that it is not located.

  Under this assumption, the route guidance system 1 includes a multimodal route including a route to the EV parking lot Pb that is within the cruising range La and has the lowest train fare (indicated by broken arrows in FIG. 1). Will be searched and guided.

  Further, it is assumed that the road between the branch point P11 and the branch point P14 is a road with a downward slope, and when the EV vehicle C travels between the branch point P11 and the branch point P14, the amount of charge increases and the vehicle can continue. The distance is significantly increased, and the cruising distance L17 of the EV vehicle C at the point P17 located between the branch point P11 and the branch point P14 is "(distance c1 + distance g) <(distance c1 + distance d + distance e + distance j) <navigable. It is assumed that it is calculated so as to satisfy the relationship with the distance L17 ".

  Under these assumptions, the route guidance system 1 has a multimodal route (a broken line in FIG. 1) including a route to the EV parking lot Pb that is within the cruising distance La and has the lowest train fare at the branch point P11. However, at the point P17, a multimodal route including the route to the EV parking lot Pc within the cruising range L17 and having the lowest train fare (see FIG. 1 (indicated by a solid arrow in FIG. 1). In this way, in the route guidance system 1, when the cruising range is increased, the extended cruising range can be effectively utilized.

  In the first embodiment described above, the in-vehicle device 10 is mounted on the EV vehicle C, acquires the current location information and destination information of the EV vehicle C, and calculates the cruising distance of the EV vehicle C. These current location information, destination information, and cruising range information are transmitted to the vehicle management center 20 by wireless communication. The vehicle management center 20 manages the current location information, destination information, and cruising range information received by wireless communication for each EV vehicle C, and is a route from the current location to the destination using both the EV vehicle C and a train. From the current location to the EV parking lot, use the EV vehicle C, use the train from the station with the EV parking lot to the nearest station, and walk from the nearest station to the destination The multi-modal route that is the route traveled by is searched, and the searched multi-modal route information is transmitted to the in-vehicle device 10 by wireless communication. The in-vehicle device 10 also guides the multimodal route using the current location information and the multimodal route. The vehicle management center 20 is an EV parking lot located within a cruising distance from the current location among the EV parking lots of the station attached to the train, and the train fee to the nearest station of the destination is The multimodal route including the route to the EV parking lot that is the cheapest is searched, and the multimodal route is re-searched based on the fact that a certain time has passed since the multimodal route was searched and determined. . As a result, for example, when the cruising distance is significantly increased, the train fee to the nearest station at the destination can be reduced. In this way, when the cruising distance increases, the extended cruising distance can be effectively utilized. In addition, since the train fee to the nearest station of the destination can be made cheaper, the user's economic burden can be reduced.

  In the first embodiment, the in-vehicle device 10 is mounted on the EV vehicle C, calculates the SOC information of the EV vehicle C, and transmits the calculated SOC information to the vehicle management center 20 by wireless communication. To do. The vehicle management center 20 manages the searched multimodal route information and the SOC information received by wireless communication for each EV vehicle C, predicts the charging power in each grid where the EV parking lot on the multimodal route is located, and The charging power prediction information, which is information related to the predicted charging power, is provided to the grid power supply management center 30 that manages the power supply to each grid. Thereby, the charge power amount prediction information and the grid information can be provided to the grid power supply management center 30, that is, the power company. The power company can provide the charge power amount prediction information and the grid provided from the route guidance system 1. Based on the information, it is possible to make a power supply plan in units of grids, and to supply power to each grid according to the power supply plan that has been established, and thus to supply power to each grid to meet the power needs. Will be able to.

(Second Embodiment)
Next, a second embodiment of the route guidance system according to the present invention will be described with reference to FIGS. FIG. 8 is a diagram corresponding to FIG. 1 described above, and is a diagram illustrating the overall configuration of the route guidance system 2 including the grid power supply management center 30. FIGS. 9 and 10 are flowcharts corresponding to FIG. 4 and showing a processing procedure of the multimodal route guidance process S100a executed by the in-vehicle device 10. FIG. 11 is a flowchart showing the processing procedure of the multimodal route search processing S200a executed by the vehicle management center 20.

  In the route guidance system 1 according to the first embodiment, the multimodal route is searched again every time a certain time has elapsed since the multimodal route is searched and determined. In the route guidance system 2, after the multimodal route is searched and determined, when the EV vehicle C reaches the vicinity of the EV parking lot on the multimodal route, the multimodal route is searched again. Thereby, compared with the route guidance system 1, while reducing the calculation load concerning the route guidance system 2, it is going to reduce the communication amount of the radio | wireless communication between the vehicle equipment 10 and the vehicle management center 20. FIG.

  Specifically, as shown in FIG. 9, when the in-vehicle device 10 finishes the process of the previous step S101 and proceeds to the process of step S103a, the destination information, the current location information, the cruising range information, and the route search A signal indicating the execution instruction is transmitted to the vehicle management center 20. That is, in the second embodiment, unlike the first embodiment, the in-vehicle device 10 does not sequentially transmit the current location information and the cruising range information. And the vehicle equipment 10 will transfer to the process of the following step S107, if the process of step S103a is performed.

  Moreover, as shown in FIG. 10, the vehicle equipment 10 will judge whether the EV vehicle C reached | attained the periphery of EV parking lot, if the process of previous step S111 is complete | finished and it transfers to the judgment process of step S123. . Here, the EV vehicle C has reached the periphery of the EV parking lot. The radius is a fixed distance (for example, “5 [km]”) centering on the EV parking lot on the multimodal route that has already started guidance. It means that you have reached the circle.

  Here, when the in-vehicle device 10 determines that the EV vehicle C has reached the vicinity of the EV parking lot (“Yes” in the determination processing in step S123), the in-vehicle device 10 re-searches the multimodal route as the processing in subsequent step S125. Therefore, the present location information and the cruising range information are transmitted to the vehicle management center 20 by wireless communication. On the other hand, when the in-vehicle device 10 does not determine that the EV vehicle C has reached the vicinity of the EV parking lot (“No” in the determination process in step S123), the in-vehicle device 10 executes the determination process in step S123 again.

  Further, as shown in FIG. 11, the vehicle management center 20 determines whether or not to receive a signal indicating destination information, current location information, cruising range information, and a route search execution instruction as the determination process in step S201a. to decide. Here, when these various information and signals are not received (“No” in the determination process of step S201a), the vehicle management center 20 executes the determination process of step S201a again. On the other hand, when such various information and signals are received (“Yes” in the determination process of step S201a), the vehicle management center 20 proceeds to the subsequent process of step S205. In other words, in the second embodiment, unlike the first embodiment, the vehicle management center 20 does not receive these information sequentially.

  Further, when the vehicle management center 20 transmits the multimodal route information as the processing of step S213, the vehicle management center 20 receives the current location information and the cruising distance information transmitted from the in-vehicle device 10 by wireless communication as the determination processing of step S215a. Determine whether or not. Here, when the current location information and the cruising range information are received (“Yes” in the determination process of step S215a), the vehicle management center 20 proceeds to the process of the previous step S207 and searches for a multimodal route again. . On the other hand, when the current location information and the cruising distance information are not received (“No” in the determination process of step S215a), the vehicle management center 20 proceeds to the determination process of the previous step S217.

  An operation example of the route guidance system 2 configured as described above will be described with reference to FIG. As shown in FIG. 8, the branch points P11 to P16, the point P27, the parking lot Pa, and the EV parking lots Pb and Pc are separated by a distance a to a distance i and a distance c2. The point P27 is a point on the circle C2 that is on the multimodal route searched for at the branch point P11 and has a radius of a certain distance from the EV parking lot Pb.

  Here, the cruising distance La of the EV vehicle C at the branch point P11 is “(distance a + distance f) <(distance a + distance b + distance c + distance g) <distance cruising distance La <(distance a + distance b + distance c + distance d + distance”. It is assumed that it is calculated so as to satisfy the relationship of “e + distance j)”. In other words, although the parking lot Pa and the EV parking lot Pb are located within the cruising distance of the EV vehicle C at the branch point P11, the EV parking lot Pc is within the cruising distance of the EV vehicle C at the branch point P11. Assume that it is not located.

  Under this assumption, the route guidance system 1 includes a multimodal route including a route to the EV parking lot Pb that is within the cruising range La and has the lowest train fare (indicated by broken arrows in FIG. 8). Will be searched and guided.

  Further, it is assumed that the road between the branch point P11 and the branch point P14 is a road with a downward slope, and when the EV vehicle C travels between the branch point P11 and the branch point P14, the amount of charge increases and the vehicle can continue. The distance is significantly increased, and the cruising distance L27 of the EV vehicle C at the point P27 located between the branch point P11 and the branch point P14 is "(distance c2 + distance g) <(distance c2 + distance d + distance e + distance j) <navigable. It is assumed that it is calculated so as to satisfy the relationship with the distance L27 ".

  Under these assumptions, the route guidance system 2 has a multimodal route (a broken line in FIG. 8) including a route to the EV parking lot Pb that is within the cruising distance La and has the lowest train fare at the branch point P11. However, at the point P27, a multimodal route including the route to the EV parking lot Pc that is within the cruising range L27 and has the lowest train fare (see FIG. 8 (indicated by a solid arrow in FIG. 8). In this way, in the route guidance system 1, when the cruising range is increased, the extended cruising range can be effectively utilized.

  In the second embodiment described above, it is possible not only to obtain operational effects according to the first embodiment, but also to obtain the following operational effects. It also becomes. That is, in the route guidance system 2, after the multimodal route is searched and determined, when the EV vehicle C reaches the vicinity of the EV parking lot on the multimodal route, the multimodal route is searched again. . As a result, the calculation load related to the route guidance system 2 is reduced as compared with the route guidance system 1 that searches for the multimodal route again every time a predetermined time has elapsed since the search and determination of the multimodal route. The amount of wireless communication between the machine 10 and the vehicle management center 20 can be reduced.

FIG. 15 is a diagram showing a determination table used in the multimodal route search process S200b.

  In the route guidance system 1 of the first embodiment, the multimodal route is searched again every time a certain time has elapsed since the search and determination of the multimodal route. However, the route guidance system 1 of the third embodiment In the route guidance system 3, after the multimodal route is searched and determined, when the EV vehicle C reaches a branch point on the guided multimodal route, the multimodal route is searched again. Thereby, compared with the route guidance system 1, while reducing the calculation load concerning the route guidance system 3, it is going to reduce the communication amount of the radio | wireless communication between the vehicle equipment 10 and the vehicle management center 20. FIG.

  Specifically, as shown in FIG. 13, when the in-vehicle device 10 finishes the process of step S111 (see FIG. 9) and proceeds to the determination process of step S123b, the multimodal route that the EV vehicle C is guiding is shown. It is determined whether or not the upper branch point has been reached. Here, the fact that the EV vehicle C has reached the branch point on the multimodal route being guided is a branch point on the multimodal route that has already started guidance, and is in front of the EV parking lot (that is, the relevant point) This means that a branch point located on the EV vehicle C side) has been reached.

  Here, when the in-vehicle device 10 determines that the EV vehicle C has reached the branch point (“Yes” in the determination process of step S123b), the current position is determined so as to re-search the multimodal route as the process of step S125. Information and cruising range information are transmitted to the vehicle management center 20 by wireless communication. On the other hand, when the in-vehicle device 10 does not determine that the EV vehicle C has reached the branch point (“No” in the determination process of step S123b), the in-vehicle device 10 executes the determination process of step S123b again.

  Further, as shown in FIG. 14, the vehicle management center 20 uses the determination table Tb1 shown in FIG. 15 in addition to the destination information, the current location information, the cruising range information, and the fare information as a process of step S207a. Among the EV parking lots of the station attached to the train, it is an EV parking lot located within the cruising distance from the branch point on the multimodal route being guided, and the fare to the destination is the cheapest A multimodal route including a route to the EV parking lot is searched.

  A method of using the determination table Tb1 will be described with reference to FIGS. When the EV vehicle C reaches the branch point P11, the vehicle management center 20 determines that the cruising distance La calculated at the branch point P11 is “(distance a + distance b + distance c + distance g) + (distance g + distance c + distance b + distance”. f) "or more, it is determined that the EV parking lot Pb is within the cruising distance of the EV vehicle C at the branch point P11. Further, when the EV vehicle C reaches the branch point P12, the vehicle management center 20 determines that the cruising distance Lb calculated at the branch point P12 is “(distance b + distance c + distance g) + (distance g + distance c + distance b + distance”. f) ”, it is determined that the EV parking lot Pb is within the cruising distance of the EV vehicle C at the branch point P12. When the EV vehicle C reaches the branch point P13, the vehicle management center 20 determines that the cruising distance Lc calculated at the branch point P13 is “(distance c + distance d + distance e + distance j) + (distance j + distance e + distance”. d + distance g) ”or more, it is determined that the EV parking lot Pc is within the cruising distance of the EV vehicle C at the branch point P13. When the EV vehicle C reaches the branch point P14, the vehicle management center 20 determines that the cruising distance Ld calculated at the branch point P14 is “(distance d + distance e + distance j) + (distance j + distance e + distance d + distance”. g) ”, it is determined that the EV parking lot Pc is within the cruising distance of the EV vehicle C at the branch point P14.

  In this way, the vehicle management center 20 is located within the cruising distance of the EV vehicle C at the branch point where the EV parking lot of the station closest to the destination is next to the nearest station at the branch point. As for whether or not “the EV vehicle C can travel at the branch point from the branch point to the EV parking lot of the nearest station of the destination next to the nearest station of the branch point” Whether the distance along the route is equal to or greater than the sum of the distance along the route from the EV parking lot of the nearest station of the destination to the EV parking lot of the nearest station of the branch point Judgment based on "No".

  An operation example of the route guidance system 3 configured as described above will be described with reference to FIG. As shown in FIG. 12, the EV parking lot Pa that the station Sa located in the grid G1 has, the EV parking lot Pb that the station Sb located in the grid G2 has, and the EV that the station Sc located in the grid G3 has. Charging facilities for charging the EV vehicle C are respectively installed in the parking lot Pc. Further, the branch points P11 to P16 and the EV parking lots Pa to Pc are separated by a distance a to a distance i as shown in FIG.

  Here, the cruising distance Lb of the EV vehicle C at the branch point P12 satisfies the relationship “{(distance b + distance c + distance g) + (distance g + distance c + distance b + distance f)} <cruising range Lb”. It is assumed that it is calculated as follows. In other words, the cruising distance Lb at the branch point P12 is equal to or greater than the sum of the distance along the route from the branch point P12 to the EV parking lot Pb and the distance along the route from the EV parking lot Pb to the EV parking lot Pa. Suppose that

  Under this assumption, the route guidance system 3 includes a multimodal route including a route to the EV parking lot Pb that is within the cruising distance Lb and has the lowest train fare (indicated by broken arrows in FIG. 12). Will be searched and guided.

  Further, it is assumed that the road from the branch point P11 to the branch point P14 is a road with a downward slope. When the EV vehicle C travels from the branch point P12 to the branch point P13, the amount of charge increases and the cruising distance is possible. Is significantly extended, and the cruising distance Lc of the EV vehicle C at the branch point P13 located between the branch points P11 and P14 is “{(distance c + distance d + distance e + distance j) + (distance j + distance e + distance d + distance”. g)} <The cruising range Lc ”is assumed to be calculated.

  Under these assumptions, the route guidance system 3 has a multimodal route (a broken line in FIG. 12) including a route to the EV parking lot Pb that is within the cruising distance Lb and has the lowest train fare at the branch point P12. However, at the branch point P13, a multimodal route (including a route to the EV parking lot Pc, which is within the cruising range Lc and has the lowest train fare), is detected and guided. 12 (shown by a solid line arrow in FIG. 12). In this way, in the route guidance system 3, when the cruising range is increased, the extended cruising range can be effectively utilized.

  Further, it is assumed that the road from the branch point P11 to the branch point P14 is a road with a downward slope. When the EV vehicle C travels from the branch point P12 to the branch point P13, the amount of charge increases and the cruising distance is possible. , And the EV vehicle C's cruising distance Lc at the branch point P13 is “(distance c + distance d + distance e + distance j) <navigable distance Lc <{(distance c + distance d + distance e + distance j) + (distance j + distance e + It is assumed that it is calculated so as to satisfy the relationship of “distance d + distance g)}”.

  Under these assumptions, the route guidance system 3 has a multimodal route (a broken line in FIG. 12) including a route to the EV parking lot Pb that is within the cruising distance Lc and has the lowest train fare at the branch point P13. (Indicated by the arrow).

  In the route guidance system 1 of the first embodiment or the route guidance system 2 of the second embodiment, for example, the EV vehicle C is heavily congested while traveling between the branch point P16 and the EV parking lot Pc. If the EV parking lot Pc becomes full while the EV vehicle C is traveling between the branch point P16 and the EV parking lot Pc, the EV vehicle C is not fully charged. There may be a situation in which it is impossible to return to the parking lot Pb.

  However, in the route guidance system 3 of the present embodiment, even in such a case, the EV vehicle C has a margin for the distance along the route from the EV parking lot Pc to the EV parking lot Pb. There is almost no such a situation that cannot be returned to the EV parking lot Pb due to a lack of charge.

  In the third embodiment described above, it is possible not only to obtain operational effects according to the first embodiment, but also to obtain the following operational effects. It also becomes. That is, in the route guidance system 3, after searching for and determining a multimodal route, when the EV vehicle C reaches a branch point on the guided multimodal route, the multimodal route is searched again. Thus, every time a predetermined time has elapsed since the search and determination of the multimodal route, the calculation load related to the route guidance system 3 is reduced more than the route guidance system 1 that searches for the multimodal route again, and the vehicle is mounted on the vehicle. The amount of wireless communication between the machine 10 and the vehicle management center 20 can be reduced.

  Further, in the route guidance system 3, whether or not the EV parking lot of the station closest to the destination next to the branch station is within the cruising distance of the EV vehicle C at the branch point. "The EV vehicle C's cruising distance at the branch point is the route from the branch point to the EV parking lot of the nearest station at the destination next to the nearest station at the branch point. Whether or not the distance along the route is the sum of the distance along the route from the EV parking lot of the nearest station of the destination to the EV parking lot of the nearest station of the branch point The decision was made based on As a result, for example, due to traffic jams, full cars, etc., even if it becomes impossible to reach the EV parking lot attached to the nearest station of the next destination from the nearest station of the branch point, You will be able to return to the nearest station.

(Fourth embodiment)
Next, a fourth embodiment of the route guidance system according to the present invention will be described with reference to FIG. 16, FIG. 17, FIG. 18, and FIG. FIG. 16 is a diagram corresponding to FIG. 1 and FIG. 8 described above, and shows the overall configuration of the route guidance system 4 including the grid power supply management center 30. FIG. 17 is a diagram corresponding to FIG. 9 described above, and is a diagram illustrating a processing procedure of the multimodal route guidance processing S100c executed by the in-vehicle device 10. 18 is a diagram corresponding to FIG. 10 and FIG. 13 described above, and among the processing procedures of the multimodal route guidance processing S100c executed by the vehicle-mounted device 10, the processing following the processing procedure shown in FIG. It is a flowchart which shows a procedure. FIG. 19 is a flowchart corresponding to FIG. 11 and FIG. 14, and is a flowchart illustrating an example of a processing procedure of a multimodal route search process executed by the vehicle management center 20.

  In the route guidance system 1 according to the first embodiment, the multimodal route is searched again every time a certain time has elapsed since the multimodal route is searched and determined. In the route guidance system 4, after searching and determining a multimodal route, when the EV vehicle C reaches a re-search point set by a user operation, the multimodal route is searched again. Thereby, compared with the route guidance system 1, while reducing the calculation load concerning the route guidance system 4, it is going to reduce the communication amount of the radio | wireless communication between the vehicle equipment 10 and the vehicle management center 20. FIG.

  Specifically, the user of the in-vehicle device 10 operates the appropriate input device that constitutes the operation unit 13, thereby performing destination information that is destination information, a route search execution instruction, and route guidance. In addition to the start instruction, re-search point information that is information on a re-search point for re-searching the multimodal route can be input. The operation unit 13 corresponds to re-search point information acquisition means described in the claims.

  As shown in FIG. 17, when the execution of the multimodal route guidance process S100c is started, the in-vehicle device 10 first receives destination information, re-search point information, and a route search execution instruction as a determination process in step S101c. 13 determines whether or not the input has been made. Here, when the destination information, the re-search point information, and the route search execution instruction are not input (“No” in the determination process of Step S101c), the vehicle-mounted device 10 executes the determination process of Step S101c again. On the other hand, when the destination information, the re-search point information, and the route search execution instruction are input (“Yes” in the determination process of step S101c), the in-vehicle device 10 proceeds to the subsequent process of step S103c. When the process proceeds to step S103c, the vehicle-mounted device 10 transmits a signal indicating destination information, current location information, cruising range information, re-search point information, and a route search execution instruction to the vehicle management center 20, and subsequent steps. The process proceeds to S107.

  Also, as shown in FIG. 18, when the in-vehicle device 10 finishes the process of step S111 (see FIG. 17) and proceeds to the determination process of step S123c, whether the EV vehicle C has reached the re-search point or not. Judging.

  Here, when the in-vehicle device 10 determines that the EV vehicle C has arrived at the re-search point (“Yes” in the determination process of step S123c), as the subsequent process of step S125, to re-search the multimodal route, Current location information and cruising range information are transmitted to the vehicle management center 20 by wireless communication. On the other hand, when the in-vehicle device 10 does not determine that the EV vehicle C has arrived at the re-search point (“No” in the determination process in step S123c), the vehicle-mounted device 10 executes the determination process in step S123c again.

  As shown in FIG. 19, the vehicle management center 20 receives the destination information, current location information, cruising range information, re-search point information, and a signal indicating a route search execution instruction as the determination process in step S201c. Judge whether to do. Here, when these various information and signals are not received (“No” in the determination process of step S201c), the vehicle management center 20 executes the determination process of step S201c again. On the other hand, when such various information and signals are received (“Yes” in the determination process of step S201c), the vehicle management center 20 proceeds to the subsequent process of step S205. The vehicle management center 20 stores the re-search point information received from the in-vehicle device 10 in the center-side storage unit 21. Thus, the user of the EV vehicle C (that is, the in-vehicle device 10) can register the re-search point in the vehicle management center 20.

  An example of the operation of the route guidance system 4 configured as described above will be described with reference to FIG. As shown in FIG. 16, the branch points P11 to P16 and the EV parking lots Pa to Pc are separated by a distance a to a distance i. The re-search points P47 to P49 are points registered by a user operation at the operation unit 13.

  Here, the cruising distance La of the EV vehicle C at the branch point P11 is “(distance a + distance f) <(distance a + distance b + distance c + distance g) <distance cruising distance La <(distance a + distance b + distance c + distance d + distance”. It is assumed that it is calculated so as to satisfy the relationship of “e + distance j)”. In other words, although the parking lot Pa and the EV parking lot Pb are located within the cruising distance of the EV vehicle C at the branch point P11, the EV parking lot Pc is within the cruising distance of the EV vehicle C at the branch point P11. Assume that it is not located.

  Under this assumption, the route guidance system 4 has a multimodal route including the route to the EV parking lot Pb that is within the cruising range La and has the lowest train fare (indicated by broken arrows in FIG. 16). Will be searched and guided.

  Further, it is assumed that the road between the branch point P11 and the branch point P14 is a road with a downward slope, and when the EV vehicle C travels between the branch point P11 and the branch point P14, the amount of charge increases and the vehicle can continue. The distance significantly increases and the cruising distance L47 of the EV vehicle C at the re-search point P47 set between the branch point P13 and the branch point P14 is “(distance c3 + distance g) <(distance c3 + distance d + distance e + distance j) < It is assumed that it is calculated so as to satisfy the relationship with the cruising range L47 ".

  Under these assumptions, the route guidance system 4 has a multimodal route (a broken line in FIG. 16) including a route to the EV parking lot Pb that is within the cruising distance La and has the lowest train fare at the branch point P11. In the re-search point P47, a multimodal route including a route to the EV parking lot Pc that is within the cruising range L47 and has the lowest train fare is provided at the re-search point P47. (Indicated by a solid arrow in FIG. 16) is searched and guided. Thus, in the route guidance system 4, when the cruising range is increased, the extended cruising range can be effectively utilized.

  In the fourth embodiment described above, it is possible not only to obtain operational effects according to the first embodiment, but also to obtain the following operational effects. It also becomes. That is, in the route guidance system 4, after searching and determining a multimodal route, when the EV vehicle C reaches a re-search point registered by a user operation, the multimodal route is searched again. The user can reduce the number of re-searches for multi-modal routes by registering an appropriate number of re-search points at appropriate positions such as the vicinity of branch points on the multi-modal route. Every time a fixed time elapses after the determination, the EV vehicle C branches again on the multimodal route after the route guidance system 1 that searches the multimodal route again or after searching and determining the multimodal route. When the point is reached, the calculation load related to the route guidance system 4 is reduced more than the route guidance system 3 that searches for a multimodal route again, and the wireless communication between the vehicle-mounted device 10 and the vehicle management center 20 is reduced. The amount of communication can be reduced.

(Fifth embodiment)
Next, a fifth embodiment of the route guidance system according to the present invention will be described with reference to FIG. 20, FIG. 21, FIG. 22, and FIG. FIG. 20 is a diagram corresponding to FIG. 16 and the like, and is a diagram illustrating an overall configuration of the route guidance system 5 including the grid power supply management center 30. FIG. 21 is a diagram corresponding to FIG. 17 and the like, and is a diagram illustrating a processing procedure of the multimodal route guidance process S100d executed by the in-vehicle device 10. FIG. 22 is a diagram corresponding to FIG. 18 and the like, and is a flowchart showing a processing procedure following the processing procedure shown in FIG. 21 among the processing procedures of the multimodal route guidance process S100d executed by the in-vehicle device 10. It is. FIG. 23 is a flowchart corresponding to FIG. 19 and the like, and is a flowchart illustrating an example of a processing procedure of a multimodal route search process executed by the vehicle management center 20.

  In the route guidance system 4 according to the fourth embodiment, after the multimodal route is searched and determined, when the EV vehicle C reaches the re-search point registered by the user operation, the multimodal route is searched again. However, in the route guidance system 5 according to the fifth embodiment, after searching and determining a multimodal route, the EV vehicle C is adjacent to the re-search point registered by the user operation and the registered re-search point. When a re-search area including a branch point to be reached is reached, a multimodal route is searched again. Thereby, compared with the route guidance system 4, while reducing the calculation load concerning the route guidance system 5, it is going to reduce the communication amount of the radio | wireless communication between the vehicle equipment 10 and the vehicle management center 20. FIG.

  Specifically, the user of the in-vehicle device 10 operates the appropriate input device that constitutes the operation unit 13, thereby performing destination information that is destination information, a route search execution instruction, and route guidance. In addition to the start instruction, re-search point information that is information on a re-search point for re-searching the multimodal route can be input. When the re-search point information is input, the in-vehicle device 10 sets a re-search area that is a circular area that includes at least one adjacent branch point with the re-search point as the center. The operation unit 13 corresponds to a re-search area information acquisition unit described in the claims.

  As shown in FIG. 21, when the execution of the multimodal route guidance process S100d is started, the in-vehicle device 10 first performs destination information, a re-search point (that is, a re-search area), and a route search as a determination process in step S101d. It is determined whether or not an execution instruction is input from the operation unit 13. Here, when the destination information, the re-search area information that is information on the re-search area, and the route search execution instruction are not input (“No” in the determination process of step S101d), the vehicle-mounted device 10 performs step S101d. When the destination information, the re-search area information, and the route search execution instruction are input ("Yes" in the determination process in step S101d), the vehicle-mounted device 10 proceeds to the subsequent step S103d. Transition to processing. When the process proceeds to step S103d, the vehicle-mounted device 10 transmits a signal indicating destination information, current location information, cruising range information, re-search area information, and a route search execution instruction to the vehicle management center 20, and subsequent steps. The process proceeds to S107.

  Further, as shown in FIG. 22, when the in-vehicle device 10 finishes the process of step S111 (see FIG. 21) and proceeds to the determination process of step S123d, whether or not the EV vehicle C has reached the re-search area. Determine whether.

  Here, when the in-vehicle device 10 determines that the EV vehicle C has reached the re-search area (“Yes” in the determination process of step S123d), the in-vehicle device 10 should re-search for the multimodal route as the process of subsequent step S125. The current location information and the cruising range information are transmitted to the vehicle management center 20 by wireless communication. On the other hand, when the in-vehicle device 10 does not determine that the EV vehicle C has reached the re-search area (“No” in the determination process in step S123d), the in-vehicle device 10 executes the determination process in step S123d again.

  As shown in FIG. 23, the vehicle management center 20 receives the destination information, current location information, cruising range information, re-search area information, and a signal indicating a route search execution instruction as the determination process in step S201d. Judge whether to do. Here, when the various information and signals are not received (“No” in the determination process in step S201d), the vehicle management center 20 executes the determination process in step S201d again. On the other hand, when such various information and signals are received (“Yes” in the determination process of step S201d), the vehicle management center 20 proceeds to the subsequent process of step S205. The vehicle management center 20 stores the re-search area information received from the in-vehicle device 10 in the center-side storage unit 21. In this way, the user of the EV vehicle C (that is, the in-vehicle device 10) can register the re-search area in the vehicle management center 20.

  An example of the operation of the route guidance system 5 configured as described above will be described with reference to FIG. As shown in FIG. 20, the branch points P11 to P16 and the EV parking lots Pa to Pc are separated by a distance a to a distance i. The re-search points P47 and P49 are points determined by a user operation on the operation unit 13, and the in-vehicle device 10 includes a branch point P13 adjacent to the re-search point P47 with the re-search point P47 as the center. A re-search area A57 which is a circular area is set, and a re-search area A59 which is a circular area including branch points P15 and P16 adjacent to the re-search point P49 with the re-search point P49 as the center is set.

  Here, the cruising distance La of the EV vehicle C at the branch point P11 is “(distance a + distance f) <(distance a + distance b + distance c + distance g) <distance cruising distance La <(distance a + distance b + distance c + distance d + distance”. It is assumed that it is calculated so as to satisfy the relationship of “e + distance j)”. In other words, although the parking lot Pa and the EV parking lot Pb are located within the cruising distance of the EV vehicle C at the branch point P11, the EV parking lot Pc is within the cruising distance of the EV vehicle C at the branch point P11. Assume that it is not located.

  Under this assumption, the route guidance system 5 has a multimodal route including the route to the EV parking lot Pb that is within the cruising range La and has the lowest train fare (indicated by broken arrows in FIG. 20). Will be searched and guided.

  Further, it is assumed that the road between the branch point P11 and the branch point P14 is a road with a downward slope, and when the EV vehicle C travels between the branch point P11 and the branch point P14, the amount of charge increases and the vehicle can continue. The cruising distance L57 of the EV vehicle C at the point where it reaches the re-search area A57 set around the re-search point P47 registered between the branch point P13 and the branch point P14 is “(distance c3 + distance). g) <(Distance c3 + Distance d + Distance e + Distance j) <It is assumed that the distance is calculated so as to satisfy the relationship of cruising range L57.

  Under these assumptions, the route guidance system 5 has a multimodal route (a broken line in FIG. 20) including a route to the EV parking lot Pb that is within the cruising distance La and has the lowest train fare at the branch point P11. The route to the EV parking lot Pc that is within the cruising range L57 and has the lowest train fare at the point that has reached the re-search area A57. A multimodal route (indicated by a solid arrow in FIG. 20) is searched and guided. In this way, in the route guidance system 5, when the cruising range is extended, the extended cruising range can be effectively used.

  In the fifth embodiment described above, it is possible not only to obtain operational effects according to the first embodiment, but also to obtain the following operational effects. It also becomes. That is, in the route guidance system 5, after searching for and determining a multimodal route, the EV vehicle C has reached a re-search area including a re-search point registered by a user operation and a branch point adjacent to the re-search point. In this case, it was decided to search for a multimodal route again. The user can reduce the number of re-searches for multi-modal routes by setting an appropriate number of re-search points at appropriate positions such as near a branch point on the multi-modal route. Every time a fixed time elapses after the determination, the EV vehicle C branches again on the multimodal route after the route guidance system 1 that searches the multimodal route again or after searching and determining the multimodal route. When the point is reached, the calculation load related to the route guidance system 5 is reduced more than the route guidance system 3 that searches for a multimodal route again, and the wireless communication between the vehicle-mounted device 10 and the vehicle management center 20 is reduced. The amount of communication can be reduced. In addition, since the re-search point may be roughly determined, the burden on the user related to the operation of the in-vehicle device 10 can be reduced as compared with the route guidance system 4.

(Sixth embodiment)
Next, a sixth embodiment of the route guidance system according to the present invention will be described with reference to FIG. 24, FIG. 25, the previous FIG. 10, and FIG. Note that FIG. 24 is a diagram corresponding to FIG. 20 and the like, and is a diagram illustrating the overall configuration of the route guidance system 6 including the grid power supply management center 30. FIG. 25 is a diagram corresponding to FIG. 21 and the like, and is a diagram illustrating a processing procedure of the multimodal route guidance processing S100e executed by the in-vehicle device 10. FIG. 26 is a flowchart corresponding to FIG. 23 and the like, and is a flowchart illustrating an example of a processing procedure of a multimodal route search process executed by the vehicle management center 20.

  The route guidance system 6 according to the sixth embodiment is a route from the current location to the destination via the stop using both the EV vehicle C and the train, and uses the EV vehicle C from the current location to the EV parking lot. For the round trip between the station with the EV parking lot and the nearest station of the stop, use the train, move on foot from the nearest station to the stop, and from the EV parking lot to the destination Is searched for a multimodal route which is a route using the EV vehicle C. Further, in the route guidance system 6, the user of the EV vehicle C leaves the EV parking lot where the EV vehicle C is parked by the scheduled time when the user of the EV vehicle C returns from the stop to the EV parking lot where the EV vehicle C is parked using a train. Then, a multimodal route including a route to the EV parking lot that can charge the EV vehicle C with the amount of charge necessary to reach the destination is searched. Thereby, when the user of the EV vehicle C departs from the parking lot toward the destination, it is not necessary to worry about the shortest cruising distance due to the insufficient charge amount. Trying to relieve anxiety.

  Specifically, the user of the EV vehicle C operates the appropriate input device that constitutes the operation unit 13 to thereby perform destination information that is destination information, a route search execution instruction, and start of route guidance. In addition to the instruction, stopover information, which is information on the stopover, and a scheduled time when the user of the EV vehicle C returns to the EV parking lot where the EV vehicle C is parked from the stopover by using the train (eg, “14:00”) It is possible to input scheduled time information which is Therefore, the operation unit 13 corresponds to the stoppage information acquisition unit and the scheduled time information acquisition unit described in the claims. Note that the user of the EV vehicle C can input a point within the cruising distance when the charging state of the EV vehicle C is fully charged as a destination. Moreover, the charging facility installed in the EV parking lots Pa to Pc is a normal charging facility that is a charging facility using a normal household power source, and a charging voltage that is a voltage for charging the EV vehicle C is, for example, “100 [ V] "and the like.

  As illustrated in FIG. 25, when the execution of the multimodal route guidance process S100e is started, the in-vehicle device 10 first performs destination information, stopover information, scheduled time information, and a route search execution instruction as the determination process in step S101e. Is determined from the operation unit 13. Here, when the destination information, the stopover information, and the route search execution instruction are not input (“No” in the determination process of step S101e), the in-vehicle device 10 executes the determination process of step S101e again. When destination information, stopover information, scheduled time information, and a route search execution instruction are input (“Yes” in the determination process of step S101e), the in-vehicle device 10 proceeds to the subsequent process of step S103e. When the process proceeds to the process of step S103e, the vehicle-mounted device 10 sends a signal indicating the destination information, stopover information, scheduled time information, current location information, cruising range information, SOC information, and a route search execution instruction to the vehicle management center 20. And the process proceeds to step S107.

  Moreover, as shown in previous FIG. 10, when the vehicle equipment 10 complete | finishes the process of previous step S111 and transfers to the judgment process of step S123, it will be checked whether the EV vehicle C arrived at the periphery of EV parking lot. to decide. Here, when the in-vehicle device 10 determines that the EV vehicle C has reached the vicinity of the EV parking lot (“Yes” in the determination processing in step S123), the in-vehicle device 10 re-searches the multimodal route as the processing in subsequent step S125. Therefore, the present location information and the cruising range information are transmitted to the vehicle management center 20 by wireless communication. On the other hand, when the in-vehicle device 10 does not determine that the EV vehicle C has reached the vicinity of the EV parking lot (“No” in the determination process in step S123), the in-vehicle device 10 executes the determination process in step S123 again.

  Also, as shown in FIG. 26, the vehicle management center 20 performs destination information, stopover information, scheduled time information, current location information, cruising range information, SOC information, and route search as the determination process in step S201e. It is determined whether or not a signal indicating an instruction is received. Here, when these various information and signals are not received (“No” in the determination process of step S201e), the vehicle management center 20 executes the determination process of step S201e again. On the other hand, when such various information and signals are received (“Yes” in the determination process of step S201e), the vehicle management center 20 proceeds to the subsequent process of step S205.

  The vehicle management center 20 reads the fare information from the center-side storage unit 21 as the processing of the subsequent step S205, and as the processing of the subsequent step S207e, the destination information, stopover information, scheduled time information, current location information, SOC information, and Based on the read fare information and current time information obtained by appropriate means (not shown) in addition to the cruising distance information, from the current location among the EV parking lots of the station attached to the train. It is an EV parking lot located within the cruising distance, and is an EV parking lot that can charge the amount of charge necessary for the user to reach the destination by the scheduled return time from the stop by using the train. In addition, a multimodal route including a route to the EV parking lot where the train fee to the nearest station of the stop is the cheapest is searched.

  This EV parking lot search will be described in detail. First, the vehicle management center 20 searches for “an EV parking lot located within a cruising distance in the current location from the current location” using the current location information and the cruising range information. Next, the vehicle management center 20 uses the current location information and current time information to predict a charging start time that is the time when the EV vehicle C arrives at the EV parking lot and starts charging at the charging facility, and the prediction Using the charging start time information and the scheduled time information, which are information on the charging start time, the EV vehicle C can be charged by the charging facility installed in the EV parking lot from the charging start time to the scheduled time. The chargeable charge amount that is the amount is calculated. Further, the vehicle management center 20 uses the current location information and the SOC information to predict a charge amount of the EV vehicle C when the EV vehicle C arrives at the EV parking lot, and arrives as information on the predicted charge amount at the time of arrival. The scheduled time charge amount that is the charge amount of the EV vehicle C at the scheduled time is predicted using the hourly charge amount information and the chargeable power reception amount information that is information on the chargeable charge amount. Further, the vehicle management center 20 calculates a required charge amount that is a charge amount of the EV vehicle C that is necessary for the EV vehicle C to leave the EV parking lot and reach the destination. Then, the vehicle management center 20 uses the scheduled time charge amount information that is the information of the scheduled time charge amount and the required charge amount information that is the information of the required charge amount, to “a cruising distance from the current location to the current location”. Search for “EV parking lot whose scheduled time charging amount exceeds the required charging amount” from “EV parking lot located inside”. Furthermore, the vehicle management center 20 searches the “EV parking lot where the train fee to the nearest station on the stop is the cheapest” from the “EV parking lot where the scheduled charge amount exceeds the required charge amount”.

  In this way, when the EV parking lot is searched and a multimodal route including the route to the EV parking lot is searched, the vehicle management center 20 proceeds to the subsequent determination process of step S209.

  An example of the operation of the route guidance system 6 configured as described above will be described with reference to FIG. As shown in FIG. 24, the branch points P11 to P16, the point P27, the parking lot Pa, and the EV parking lots Pb and Pc are separated by a distance a to a distance i and a distance c2. The point P27 is a point on the circle C2 that is on the multimodal route searched for at the branch point P11 and that has a radius of a certain distance (for example, “5 [km]”) around the EV parking lot Pb. is there.

  Here, the cruising distance La of the EV vehicle C at the branch point P11 is “(distance a + distance f) <(distance a + distance b + distance c + distance g) <distance cruising distance La <(distance a + distance b + distance c + distance d + distance”. It is assumed that it is calculated so as to satisfy the relationship of “e + distance j)”. In other words, although the parking lot Pa and the EV parking lot Pb are located within the cruising distance of the EV vehicle C at the branch point P11, the EV parking lot Pc is within the cruising distance of the EV vehicle C at the branch point P11. Assume that it is not located.

  Furthermore, when the EV vehicle C is parked in the EV parking lot Pa, the charge amount of the EV vehicle C at the scheduled time is lower than the charge amount required to leave the EV parking lot Pa and reach the destination. When the vehicle is parked in the EV parking lot Pb, it is assumed that the charge amount of the EV vehicle C at the scheduled time exceeds the charge amount necessary to leave the EV parking lot Pb and reach the destination.

  Under these assumptions, the route guidance system 6 is within the cruising range La, can charge the amount of charge necessary to reach the destination by the scheduled time, and the train fee is the cheapest. A multimodal route (indicated by a dashed arrow in FIG. 24) including the route to the EV parking lot Pb is searched and guided.

  Further, it is assumed that the road between the branch point P11 and the branch point P14 is a road with a downward slope, and when the EV vehicle C travels between the branch point P11 and the branch point P14, the amount of charge increases and the vehicle can continue. The distance is significantly increased, and the cruising distance L27 of the EV vehicle C at the point P27 located between the branch point P11 and the branch point P14 is "(distance c2 + distance g) <(distance c2 + distance d + distance e + distance j) <navigable. It is assumed that it is calculated so as to satisfy the relationship with the distance L27 ".

  Further, when the EV vehicle C is parked in the EV parking lot Pb, the charge amount of the EV vehicle C at the scheduled time exceeds the charge amount necessary to leave the EV parking lot Pb and reach the destination. When parking at the EV parking lot Pc, it is assumed that the charge amount of the EV vehicle C at the scheduled time exceeds the charge amount necessary to leave the EV parking lot Pc and reach the destination.

  Under such an assumption, the route guidance system 6 is located within the cruising distance La at the branch point P11, and can charge the amount of charge necessary to reach the destination by the scheduled time. In addition, a multimodal route (indicated by a broken arrow in FIG. 24) including the route to the EV parking lot Pb where the train fee is the cheapest will be searched and guided. A multi-modal route (including a route to the EV parking lot Pc that is within L27 and can be charged with the amount of charge required to reach the destination by the scheduled time and that has the lowest train fare ( 24 (indicated by solid arrows in FIG. 24) will be searched and guided. In this way, in the route guidance system 6, when the cruising range is increased, the extended cruising range can be effectively used.

  In the sixth embodiment described above, it is possible not only to obtain operational effects according to the first embodiment, but also to obtain the following operational effects. It also becomes. That is, in the route guidance system 6, the user of the EV vehicle C leaves the EV parking lot where the EV vehicle C is parked by the scheduled time when the user returns from the stop to the EV parking lot where the EV vehicle C is parked. Thus, the multi-modal route including the route to the EV parking lot that can charge the EV vehicle C with the amount of charge necessary to reach the destination is searched. Thereby, when the user of the EV vehicle C departs the EV parking lot toward the destination, the user's psychology of the EV vehicle C is eliminated by eliminating the need to worry about the lack of the cruising range due to the insufficient charge amount. Will be able to relieve mental anxiety.

  In the sixth embodiment, the EV parking lots Pa to Pc are provided with the normal charging facility that is a charging facility using a normal household power supply. However, the present invention is not limited to this. The EV parking lots Pa to Pc are rapid charging facilities that can charge the EV vehicle C using a dedicated power source that is not a normal home power source and with a charging voltage (for example, “200 [V] etc.) higher than the home power source. The charging facility may be installed, or both of the normal charging facility and the quick charging facility may be installed, and the quick charging facility is EV at a higher charging voltage than the normal charging facility. Since it is possible to charge the vehicle C, it is possible to charge the same charge amount in a shorter charging time, and when both the normal charging facility and the quick charging facility are installed. In other words, the vehicle management center 20 calculates the chargeable charge amount according to the type of charging facility.
